BACKGROUND 1. Technical Field

The disclosure relates to a display device, and, to a transparentdisplay device.

2. Description of the Related Art

Display technology including display devices for processing anddisplaying large amounts of information continues to be rapidlydeveloped. Examples of display devices which are the focus of researchand development include a liquid crystal display (LCD) device, a plasmadisplay panel (PDP), a field emission display (FED) device, anelectroluminescence display (ELD) device, and an organic light emittingdiode (OLED) display device.

In recent years, a vast majority of research has been carried out ontransparent display devices. Transparent display devices allow a user toview an object or background disposed at the back of the display device.The transparent display devices have advantages in terms of spaceutilization, interior and design and are applicable to various uses andfields. The transparent display devices implement informationrecognition, information processing, and information display functionsusing transparent electronic devices, thereby addressing spatial andvisual limitations of existing electronic devices. For example,transparent display devices may be applied to windows of buildings orvehicles and may be implemented as smart windows that show a backgroundor display an image.

The transparent display device may be implemented as an OLED displaydevice. In this case, the transparent display device may be divided intotransmitting portions that transmit incident light as it is and lightemitting portions that emit light. When the light emitting portions donot emit light, a user may view a background at the back of thetransparent display device through the transmitting portions, and, whenthe light emitting portions emit light, the user may view an imagedisplayed by the light emitting portions.

It is to be understood that this background of the technology sectionis, in part, intended to provide useful background for understanding thetechnology. However, this background of the technology section may alsoinclude ideas, concepts, or recognitions that were not part of what wasknown or appreciated by those skilled in the pertinent art prior to acorresponding effective filing date of the subject matter disclosedherein.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Although the disclosure may be modified in various manners and haveadditional embodiments, embodiments are illustrated in the accompanyingdrawings and will be mainly described in the specification. However, thescope of the disclosure is not limited to the embodiments in theaccompanying drawings and the specification and should be construed asincluding all the changes, equivalents and substitutions included in thespirit and scope of the disclosure.

Some of the parts which are not associated with the description may notbe provided in order to describe embodiments of the disclosure and likereference numerals refer to like elements throughout the specification.

In the drawings, sizes and thicknesses of elements may be enlarged forbetter understanding clarity and ease of description thereof. However,the disclosure is not limited to the illustrated sizes and thicknesses.In the drawings, the thicknesses of layers, films, panels, regions, andother elements, may be exaggerated for clarity. In the drawings, forbetter understanding and ease of description, the thicknesses of somelayers and areas may be exaggerated.

Further, in the specification, the phrase “in a plan view” means when anobject portion is viewed from above, and the phrase “in a schematiccross-sectional view” means when a schematic cross-section taken byvertically cutting an object portion is viewed from the side.

Additionally, the terms “overlap” or “overlapped” mean that a firstobject may be above or below or to a side of a second object, and viceversa. Additionally, the term “overlap” may include layer, stack, faceor facing, extending over, covering or partly covering or any othersuitable term as would be appreciated and understood by those ofordinary skill in the art. The terms “face” and “facing” mean that afirst element may directly or indirectly oppose a second element. In acase in which a third element intervenes between the first and secondelement, the first and second element may be understood as beingindirectly opposed to one another, although still facing each other.When an element is described as ‘not overlapping’ or ‘to not overlap’another element, this may include that the elements are spaced apartfrom each other, offset from each other, or set aside from each other orany other suitable term as would be appreciated and understood by thoseof ordinary skill in the art.

When a layer, film, region, substrate, or area, is referred to as being“on” another layer, film, region, substrate, or area, it may be directlyon the other film, region, substrate, or area, or intervening films,regions, substrates, or areas, may be present therebetween. Conversely,when a layer, film, region, substrate, or area, is referred to as being“directly on” another layer, film, region, substrate, or area,intervening layers, films, regions, substrates, or areas, may be absenttherebetween. Further when a layer, film, region, substrate, or area, isreferred to as being “below” another layer, film, region, substrate, orarea, it may be directly below the other layer, film, region, substrate,or area, or intervening layers, films, regions, substrates, or areas,may be present therebetween. Conversely, when a layer, film, region,substrate, or area, is referred to as being “directly below” anotherlayer, film, region, substrate, or area, intervening layers, films,regions, substrates, or areas, may be absent therebetween. Further,“over” or “on” may include positioning on or below an object and doesnot necessarily imply a direction based upon gravity

The spatially relative terms “below”, “beneath”, “lower”, “above”,“upper”, or the like, may be used herein for ease of description todescribe the relations between one element or component and anotherelement or component as illustrated in the drawings. It will beunderstood that the spatially relative terms are intended to encompassdifferent orientations of the device in use or operation, in addition tothe orientation depicted in the drawings. For example, in the case wherea device illustrated in the drawing is turned over, the devicepositioned “below” or “beneath” another device may be placed “above”another device. Accordingly, the illustrative term “below” may includeboth the lower and upper positions. The device may also be oriented inother directions and thus the spatially relative terms may beinterpreted differently depending on the orientations.

Throughout the specification, when an element is referred to as being“connected” to another element, the element may be “directly connected”to another element, or “electrically connected” to another element withone or more intervening elements interposed therebetween. It will befurther understood that when the terms “comprises,” “comprising,”“includes” and/or “including” are used in this specification, they or itmay specify the presence of stated features, integers, steps,operations, elements and/or components, but do not preclude the presenceor addition of other features, integers, steps, operations, elements,components, and/or any combination thereof.

“About” or “approximately” as used herein is inclusive of the statedvalue and means within an acceptable range of deviation for theparticular value as determined by one of ordinary skill in the art,considering the measurement in question and the error associated withmeasurement of the particular quantity (i.e., the limitations of themeasurement system). For example, “about” may mean within one or morestandard deviations, or within ±30%, 20%, 5% of the stated value.

Although terms such as first and second are used to describe variouselements, the elements are not limited by such terms. Such terms aremerely used to differentiate one element from another element.Therefore, a first element mentioned below may also be a second elementwithin the spirit and scope of the disclosure.

In the specification and the claims, the term “and/or” is intended toinclude any combination of the terms “and” and “or” for the purpose ofits meaning and interpretation. For example, “A and/or B” may beunderstood to mean “A, B, or A and B.” The terms “and” and “or” may beused in the conjunctive or disjunctive sense and may be understood to beequivalent to “and/or.” In the specification and the claims, the phrase“at least one of” is intended to include the meaning of “at least oneselected from the group of” for the purpose of its meaning andinterpretation. For example, “at least one of A and B” may be understoodto mean “A, B, or A and B.”

Unless otherwise defined, all terms used herein (including technical andscientific terms) have the same meaning as commonly understood by thoseskilled in the art to which this disclosure pertains. It will be furtherunderstood that terms, such as those defined in commonly useddictionaries, should be interpreted as having a meaning that isconsistent with their meaning in the context of the relevant art andwill not be interpreted in an ideal or excessively formal sense unlessclearly defined in the specification.

Hereinafter, embodiments will be described with reference to theaccompanying drawings.

FIG. 1 is a perspective view of a display device according to anembodiment, and FIG. 2 is a plan view of the display device of FIG. 1.

Referring to FIGS. 1 and 2, a display device 1 may include a displaypanel 100 to display an image, a printed circuit board 300 connected tothe display panel 100, and a main circuit board 500 connected to theprinted circuit board 300.

Other types of display panels such as a liquidcrystal display (LCD) panel, a quantum dot organic light emitting diode(QD-OLED) display panel, a quantum dot liquid crystal display (LCD)panel, and a micro LED panel may also be applied as the display panel100.

The display panel 100 may include an active area AAR including pixelareas, and a non-active area NAR disposed around the active area AAR.The active area AAR may have, for example, a rectangular shape withright-angled corners or rounded corners in a plan view. The active areaAAR may have short sides and long sides. The short side of the activearea AAR may be a side extending in a first direction DR1. The long sideof the active area AAR may be a side extending in a second directionDR2. However, the shape of the active area AAR in the plan view is notlimited to the rectangular shape, and the active area AAR may also havea circular shape, an elliptical shape, or various other shapes withinthe spirit and scope of the invention. The non-active area NAR may bedisposed adjacent to both short sides and both long sides of the activearea AAR. In this case, the non-active area NAR may surround all thesides of the active area AAR and constitute the boundary of the activearea AAR. However, embodiments are not limited thereto, and thenon-active area NAR may also be disposed adjacent to only the shortsides or the long sides of the active area AAR.

The non-active area NAR of the display panel 100 may include a pad areaPR to which the printed circuit board 300 is attached. For example, thepad area PR may be disposed around one short side of the active areaAAR. However, embodiments are not limited thereto, and the pad area PRmay also be disposed around both short sides of the active area AAR ordisposed around both short sides and both long sides of the active areaAAR. Pads such as data pads may be formed in the pad area PR of thedisplay panel 100. Wires to connect the pads and driving integratedcircuits 350 to each other and wires to connect the pads and wires ofthe main circuit board 500 to each other may be formed in the printedcircuit board 300. The printed circuit board 300 may be attached ontothe pads using an anisotropic conducting film, and thus, the pads andthe wires of the printed circuit board 300 may be connected to eachother.

The non-active area NAR may include a scan driver SCP disposed at onelong side of the active area AAR. The scan driver SCP supplies gatesignals to gate lines according to a gate control signal input from atiming controller 550 which will be described below. The scan driver SCPmay be directly formed in the non-active area NAR at one outer side orboth outer sides of the active area AAR of the display panel 100 or maybe manufactured as a driving chip, mounted on a flexible film, andattached to the non-active area NAR at one outer side or both outersides of the active area AAR of the display panel 100.

The printed circuit board 300 may include a printed base film 310 andthe driving integrated circuit 350 disposed on the printed base film310. The printed base film 310 may be formed to include an insulatingmaterial.

For example, the driving integrated circuit 350 may be a data drivingintegrated circuit. The driving integrated circuit 350 may receivedigital video data and a source control signal from the timingcontroller 550. The driving integrated circuit 350 may convert thedigital video data to analog data voltages according to the sourcecontrol signal and may supply the analog data voltages to data lines.The driving integrated circuit 350 may be implemented as a driving chipand mounted on the printed base film 310 using the chip-on-film (COF)method as illustrated in FIG. 2 or directly mounted on the display panel100 using the chip-on-plastic (COP) method.

The main circuit board 500 may be attached to the printed circuit board300. Circuits implemented using driving chips may be mounted on the maincircuit board 500. For example, the timing controller 550 may be mountedon the main circuit board 500. The main circuit board 500 may be aprinted circuit board or a flexible printed circuit board.

The timing controller 550 may receive digital video data and a timingsignal from an external system board via a cable of the main circuitboard 500. Based on the timing signal, the timing controller 550 maygenerate a gate control signal for controlling an operation timing ofthe scan driver SCP and a source control signal for controlling thedriving integrated circuits 350. The timing controller 550 may supplythe gate control signal to the scan driver SCP and supply the sourcecontrol signal to the driving integrated circuits 350.

The display panel 100 may include a first substrate SUB1 and a secondsubstrate SUB2 disposed opposite to the first substrate SUB1. The firstsubstrate may be a display substrate including a light emitting elementdisposed in each pixel area, and the second substrate SUB2 may be anencapsulation substrate encapsulating the light emitting element. Thefirst substrate SUB1 and the second substrate SUB2 may be formed ofplastic or glass.

In the embodiments, the first direction DR1 and the second direction DR2are different directions which may intersect each other. For example,the first direction DR1 and the second direction DR2 indicate directionswhich intersect perpendicularly in the plan view. A third direction DR3is a direction intersecting a plane on which the first direction DR1 andthe second direction DR2 are placed. For example, the third directionDR3 indicates a direction which intersects perpendicularly with both thefirst direction DR1 and the second direction DR2. In the illustrateddrawings, the first direction DR1 indicates a horizontal direction ofthe display device 1, the second direction DR2 indicates a verticaldirection of the display device 1, and the third direction DR3 indicatesa thickness direction of the display device 1. In the followingembodiments, it may be understood that one side in the first directionDR1 indicates a rightward direction in the plan view, the other side inthe first direction DR1 indicates a leftward direction in the plan view,one side in the second direction DR2 indicates an upward direction inthe plan view, the other side in the second direction DR2 indicates adownward direction in the plan view, one side in the third direction DR3indicates an upward direction in a schematic cross-sectional view, andthe other side in the third direction DR3 indicates a downward directionin the schematic cross-sectional view. However, the directions, oneside, and the other side mentioned in the description of embodimentsshould be understood as relative directions, and the embodiments are notlimited by the mentioned directions.

The size of the first substrate SUB1 in the plan view may be larger thanthe size of the second substrate SUB2 in the plan view. The firstsubstrate SUB1 may have a shape substantially protruding beyond one sideof the second substrate SUB2. For example, a short side of the firstsubstrate SUB1 may have a shape substantially protruding beyond a shortside of the second substrate SUB2 in the second direction DR2. In otherwords, the short side of the second substrate SUB2 may have a shape thatis substantially indented compared with the short side of the firstsubstrate SUB1 in the second direction DR2. The above-described pad areaPR may be disposed in a portion of the first substrate SUB1 protrudingbeyond the second substrate SUB2.

Hereinafter, the light emitting portions will be described based on thefirst light emitting area LA1.

The first color, the second color, and the third color may be colorsdifferent from each other. The first to third colors may be any one ofred, green, and blue. For example, the first light emitting portion LA_Rmay be a red light emitting portion, the second light emitting portionLA_G may be a green light emitting portion, and the third light emittingportion LA_B may be a blue light emitting portion. However, embodimentsare not limited thereto, and the first light emitting portion LA_R maybe the green light emitting portion or the blue light emitting portion,the second light emitting portion LA_G may be a light emitting portionthat emits light of a different color from the light emitted by thefirst light emitting portion LA_R, and the third light emitting portionLA_B may be a light emitting portion that emits light of a differentcolor from the lights emitted by the first and second light emittingportions LA_R and LA_G. In the following embodiments, for convenience ofdescription, description will be given based on the case in which thered light emitting portion, the green light emitting portion, and theblue light emitting portion are arranged in that order in a directionfrom one side to the other side in the fourth direction DR4.

In some embodiments, each of the light emitting areas LA1 to LA4 mayinclude a fourth light emitting portion that emits light of a fourthcolor. The fourth color may be white. The fourth light emitting portionmay be disposed between the first light emitting portion LA_R and thesecond light emitting portion LA_G, disposed between the second lightemitting portion LA_G and the third light emitting portion LA_B,disposed at the one side in the fourth direction DR4 from the firstlight emitting portion LA_R, or disposed at the other side in the fourthdirection DR4 from the third light emitting portion LA_B.

Each of the light emitting portions LA_R, LA_G, and LA_B may have asubstantially triangular shape in the plan view. However, embodimentsare not limited thereto, and each of the light emitting portions LA_R,LA_G, and LA_B may also have other substantially polygonal shapes orother shapes such as a substantially circular shape and a substantiallyelliptical shape in the plan view.

When each of the light emitting portions LA_R, LA_G, and LA_B has asubstantially triangular shape in the plan view, the light emittingportions LA_R, LA_G, and LA_B may be arranged such that one side of eachlight emitting portion faces one side of another light emitting portionadjacent thereto. For example, one side of the first light emittingportion LA_R may face one side of the second light emitting portionLA_G, and another side of the second light emitting portion LA_G that isdifferent from the one side of the second light emitting portion LA_Gmay face one side of the third light emitting portion LA_B. In this way,the light emitting portions LA_R, LA_G, and LA_B may be arranged suchthat separation distances therebetween are minimized within a limitedlight emitting area.

The sizes of the light emitting portions LA_R, LA_G, and LA_B may besubstantially the same in the plan view. However, embodiments are notlimited thereto, and the sizes of the light emitting portions LA_R,LA_G, and LA_B in the plan view may be different from each other, or thesizes of any two may be the same or substantially the same while thesize of the remaining one is different in the plan view.

The non-light emitting area NLA may have a black bank layer and a blackmatrix disposed thereon so that output of light from the correspondingarea may be prevented. The first non-light emitting area NLA1 may have ashape surrounding the first light emitting area LA1 in the plan view.The first non-light emitting area NLA1 may be disposed between the firstlight emitting portion LAR and the second light emitting portion LA_Gand between the second light emitting portion LA_G and the third lightemitting portion LAB and may completely surround the first lightemitting area LA1. For example, the first light emitting area LA1 may becompletely surrounded by the first non-light emitting area NLA1.

The active area AAR may be formed by grouping a single lighttransmitting area and two light emitting areas together. For example,the active area AAR may be formed by grouping the first light emittingarea LA1 and the second light emitting area LA2 with the first lighttransmitting area TA1 and grouping the third light emitting area LA3 andthe fourth light emitting area LA4 with the second light transmittingarea TA2. However, embodiments are not limited thereto, and the firstlight emitting area LA1 and the third light emitting area LA3 may begrouped with the first light transmitting area TA1, the second lightemitting area LA2 and the fourth light emitting area LA4 may be groupedwith the first light transmitting area TA1, or the third light emittingarea LA3 and the fourth light emitting area LA4 may be grouped with thefirst light transmitting area TA1.

Since the active area AAR according to an embodiment is formed bygrouping a single light transmitting area and two light emitting areastogether, a larger number of light emitting areas may be disposed in thepixel area PXA which is limited, and thus it is possible to implementthe display device 1 in high resolution.

Also, since three light emitting portions that emit lights of differentcolors are disposed in each light emitting area, a separation distancebetween adjacent light emitting portions which emit lights of the samecolor is decreased, and thus it is possible to achieve high colorreproducibility when the display device 1 displays the screen by thelight emitting area.

Since three light emitting portions emit lights of different colors aredisposed in each light emitting area, a separation distance betweenadjacent light emitting portions which emit lights of the same color maybe decreased, and thus it may be possible to achieve high colorreproducibility when the display device 1 displays an image on thescreen by the light emitting area.

FIG. 7 is a plan arrangement view illustrating an active area of adisplay panel according to an embodiment.

Referring to FIG. 7, an active area AAR_1 of the display panel accordingto the embodiment may be different from the active area AAR of thedisplay panel according to the above-described embodiment in terms ofthe arrangement of light transmitting areas TAa and the arrangement oflight emitting areas LAa.

For example, referring to FIG. 7, the active area AAR_1 of the displaypanel according to the embodiment may include light transmitting areasTA1 a to TA3 a and pixel areas disposed between the light transmittingareas TA1 a to TA3 a. The pixel areas each include a light emitting areafrom which light is emitted and a non-light emitting area which does notemit light.

The pixel area may include a first pixelarea disposed between the first light transmitting area TA1 a and thesecond light transmitting area TA2 a and a second pixel area disposedbetween the first light transmitting area TA1 a and the third lighttransmitting area TA3 a. The first pixel area and the second pixel areamay extend along the column-direction extension portion CEP.

Along the shapes of the light transmitting areas TA1 a to TA1 3 adjacentthereto in the plan view, the first pixel area and the second pixel areamay have a shape in which a width gradually decreases toward a centralportion and gradually increases toward the one side and the other sidein the second direction DR2 from the central portion in the plan view.

The first pixel area may include a first light emitting area LA1 a, athird light emitting area LA3 a, and a first non-light emitting areaNLA1 a surrounding the first light emitting area LA1 a and the thirdlight emitting area LA3 a, and the second pixel area may include asecond light emitting area LA2 a, a fourth light emitting area LA4 a,and a second non-light emitting area NLA2 a surrounding the second lightemitting area LA2 a and the fourth light emitting area LA4 a. The secondlight emitting area LA2 a may be disposed at the other side in the firstdirection DR1 from the first light emitting area LA1 a, and the fourthlight emitting area LA4 a may be disposed at the other side in the firstdirection DR1 from the second light emitting area LA2 a.

Hereinafter, the light emitting portions will be described based on thefirst light emitting area LA1 a.

Each of the light emitting portions LA_Ra, LA_Ga, and LA_Ba may have asubstantially rectangular shape in the plan view. However, embodimentsare not limited thereto, and it will be apparent that each of the lightemitting portions LA_Ra, LA_Ga, and LA_Ba may also have other polygonalshapes or other shapes such as a substantially circular shape and asubstantially elliptical shape in the plan view.

When each of the light emitting portions LA_Ra, LA_Ga, and LA_Ba has asubstantially rectangular shape in the plan view, the light emittingportions LA_Ra, LA_Ga, and LA_Ba may extend such that an extendingdirection of any one light emitting portion may be different from anextending direction of the remaining light emitting portions, and thusseparation distances therebetween may be decreased. In this way, thetotal area of the light emitting areas in which the three light emittingportions are disposed may be reduced, and a larger number of lightemitting areas may be disposed in the pixel area.

For example, as illustrated in FIG. 7, the third light emitting portionLA_Ba may have a shape extending in the first direction DR1, and thefirst and second light emitting portions LA_Ra and LA_Ga may each have ashape extending in the second direction DR2.

The sizes of the light emitting portions LA_Ra, LA_Ga, and LA_Ba may besubstantially the same in the plan view. However, embodiments are notlimited thereto, and the sizes of the light emitting portions LA_Ra,LA_Ga, and LA_Ba in the plan view may be different from each other, orthe sizes of any two may be substantially the same while the size of theremaining one may be different in the plan view.

The third light emitting portion LA_Ba may be disposed at the one sidein the second direction DR2 from the first and second light emittingportions LA_Ra and LA_Ga. However, embodiments are not limited thereto,and third light emitting portion LA Ba may also be disposed at the otherside in the second direction DR2 from the first and second lightemitting portions LA_Ra and LA_Ga, or the arrangement method thereof maybe combined in various ways.

The active area AAR_1 may be formed by grouping a single lighttransmitting area and two light emitting areas together. For example,the first light transmitting area TA1 a may be grouped with the firstlight emitting area LA1 a and the second light emitting area LA2 a.However, embodiments are not limited thereto, and the first lighttransmitting area TA1 a may be grouped with the first light emittingarea LA1 a and the third light emitting area LA3 a, grouped with thesecond light emitting area LA2 a and the fourth light emitting area LA4a, or grouped with the third light emitting area LA3 a and the fourthlight emitting area LA4 a.

Since the active area AAR_1 according to the embodiment is formed bygrouping a single light transmitting area and two light emitting areastogether, a larger number of light emitting areas may be disposed in thepixel area PXA which is limited, and thus it may be possible toimplement the display device 1 in high resolution.

Also, since three light emitting portions emit lights of differentcolors are disposed in each light emitting area, a separation distancebetween adjacent light emitting portions which emit lights of the samecolor may be decreased, and thus it may be possible to achieve highcolor reproducibility when the display device 1 displays an image on thescreen by the light emitting area.

FIG. 8 is a plan arrangement view illustrating an active area of adisplay panel according to an embodiment.

Referring to FIG. 8, an active area AAR_2 of the display panel accordingto the embodiment may differ from the active area AAR of the displaypanel according to the above-described embodiment in terms of thearrangement of light transmitting areas TAb and the arrangement of lightemitting areas LAb.

FIG. 13 is a plan view illustrating a display panel of a display deviceaccording to an embodiment, and FIG. 14 is a schematic cross-sectionalview taken along lines XIV-XIV′ and XV-XV′ of FIG. 13.

Referring to FIGS. 13 and 14, a display panel 100_1 according to theembodiment may differ from the display panel 100 according to theabove-described embodiment.

For example, in the display panel 100_1 according to the embodiment, thefirst substrate SUB1_1 and the second substrate SUB2_1 may be directlycoupled to each other without a sealing member. The first substrateSUB1_1 and the second substrate SUB2_1 may be directly coupled or bondedto each other without interposing an arbitrary configuration or layertherebetween. For example, when a laser sealing device irradiates anon-active area NAR between the first substrate SUB_1 and the secondsubstrate SUB2_1 with a laser, an interface between the first substrateSUB1_1 and the second substrate SUB2_1 melts and solidifies such thatthe first substrate SUB1_1 and the second substrate SUB2_1 in thecorresponding area may be bonded to each other. In this case, the lasermay be a femtosecond (fs) laser, but embodiments are not limitedthereto.

Since the first substrate SUB1_1 and the second substrate SUB2_1 aredirectly coupled to each other without a sealing member, the displaypanel 100_1 according to the embodiment may improve a lighttransmittance in the non-active area NAR.

For example, in the display device 2 according to the embodiment, thedisplay panel 100_2 may not include the second substrate SUB2 and mayinclude a thin film encapsulation layer 180.

The thin film encapsulation layer 180 may include a first inorganicencapsulation film 181, an organic encapsulation film 182 disposed onthe first inorganic encapsulation film 181, and a second inorganicencapsulation film 183 disposed on the organic encapsulation film 182.

The thin film encapsulation layer 180 may be disposed on a commonelectrode 160. The first inorganic encapsulation film 181 of the thinfilm encapsulation layer 180 may be directly disposed on an uppersurface of the common electrode 160.

Since the display panel 100_2 according to the embodiment does notinclude the second substrate SUB2 and includes the thin filmencapsulation layer 180 to encapsulate an upper portion of the commonelectrode 160, for example, an organic light emitting element, it may bepossible to improve a light transmittance of the display device 2.

According to the display device according to an embodiment, highresolution can be realized. Therefore, when light emitting portions donot emit light, a user can view a background of the display devicethrough a light transmitting area whose size is maximized, and, when thelight emitting portions emit light, the user can view a display screenwhose resolution is further increased.
